PSRU Ratios X-Originating-IP: [66.218.79.59] To: Ken Welter One thing I can tell you is that in the last 15 plus years that I have dealt with planetaries, I still see Ford sun gears coming apart in 80% of units I take apart and I have yet to find a bad Dodge sun gear with the exception on total planet meltdown due to a plugged trans cooler.
